LAMP-BURNER,

Be it known that I, RUFUS SrAULnIndMnnnrLL,

l of HydeIPark, inthe county of Norfolk and State of Massachusetts, have invented certain new and useful Improvements in LamprBurncrs, of which the following is a specification.

My invention relates to Argand or other similar burners 11. ring a round wic'lo-tnbe; and

- Its object'is torcgulatddivide, or deflect the Currents of air which pass throughthc burner, and impinge upon the exterior of the flame, so as toproduce as perfect combustion,antl, consequently, as brilliant I The point at which I as found a best to unis divide, regulate, or deflect the, air passing up through the burner is near the top of the wick-tube, and near the base of theflame; and I therefore provide thewick-tube or the burncrat that point with a metallic. cap or flange, of suitable shape and construction, with or without perfoi'ations,eitlier scalloped or indented on its edge, or not, as preferred, which serves to dei flect the air passing up around the wick-tube 'to the flame, or to deflect, anddivide, and distribute the current-s, so that the air may be supplied to the .flameto better advantage, and'to produce a very perfect com- V bustion. l r

.TheYmanner in w'hichjmy invention is or may be carried into effect will .be readily understood by reference to the accompanying drawing, in which-- Figurel is a sectional view of an Argand or roundwick burner to which my improvement is applied.

Figure 2 is a sectional view of the removable por v tion of the burner detached from the wick. r

, Figures 3, 4, 5 6,7, and 8 are plan views of differout forms in whic l the cap may be made.

The construction of the round wick-tube shown at r a A, figrl, is too well understood to need description.

- Upon the wick-tube -is slipped the removable part of the burner 13, consisting of the chimney-holder and supporting springs,connectedwith a central sleeve,

which fits upon oraroundthe wick-tube.

; It is upon this sleeve a that the annular cap or flange b, for dividing or deflecting the air, is, in this instance, held; and I prefer, when using the sleeve (1, to form an offset or shoulder, 0, near its upper end, which will constitute thelseator support of the cap I).

The positionthat the cap occupies with relation to the wick and flame will be readily understood by reference to the drawing, and its function, as above stated,

' is to divide, deflect, and distribute mean passing up around the wick-tube to the flame.

It: is needless to say that the cap may not only be .held in position in the manner shown in the drawing,

but may be secured to the wick-tube, or supported in any othersuitable manner.

.In Argand or round-wick burners, hitherto the air h The Schedule referred to in these Letters Patent and making; part of the same.

which is intended to feed the exterior of .the flame has been permitted to pass through the burner, and around the wick-tube, in such .a manner that the course of the current is tangential to, or nearly, if not quite, parallel withthe flame, and there is, therefore, but. a comparatively small portion of this air that is brought in contact with the flame. The cap which" I employ is intended to break up and direct this current, so that it shall be cansedgto impinge at a decided angle upon the fl'amc,'or to divide the air, so that one portion shall pass up directly to the flame in a divided state,

while the other portion shall, as before, impinge against the flame, the two currents thus formed serving, by their combined action, to induce very perfect combustion of the products arising from the burning wick.

In fig. 3, I have reprcsentedan imperforated annular cap or flange, which, when fitted in place around the wick-tube, and in position relative thereto, as above explained, will deflect the current of air, so that, instead of passing up tangentially to the flame, it must pass out around the edge of thecap, and thence back toward the wick, sons to impinge against the flame at a decided angle. l The annular cap or flange may be flat, concave-convex, or of any other suitable shape, and, when made imperforate, as shown, it will serve simply to give a new direction to the upward current of air.

More satisfactory results, however, are produced by dividing theair into 'two currents, the one passing di rectly, but in a highly-divided state, to the flame, the

other being deflected outward around the edges of the cap, so as to impinge upon the flame at an angle, as in the case just described. To this end, I make use of a cap, such as shown in fig. 1-, of which the cap in fig. 4 is a plan view, of annular form, resembling the one in fig. 3, but with a series of perforations formed in it. \Vith acap such as this, the air must be divided into two currents, the one passing up through the perforations, the other being deflected outward around the edges of the cap. This form of cap, like that shown in fig. 3, is capable of many modifications for instance, the perforations, instead of bci'ng round, may be rectangular, as seen in fig. 5, or any other suitable shape.

In fig. 2, the cap is made with perforations in the top,and with sides, which extend down a distance more or less great, as desired, soas to form an annular space between the cap and the wick-tube.

Instead of perforating the cap, its edges may he notched, scalloped, or serrated, as shown in figs. 6, 7

and 8, and, under this arrangement, the air will pass up around the cap in a continuous sheet, but at varying distances from the wick-tube, owing to the irregu- Many other modifications of the cap might be made,

and these are given only by way of illustration of the various ways in which the result I aim at by the use of the cap may be secured.

Having now described my invention, and thc manner in which the same is or may be carried into effect, I would observe that deflecting plates have been used in Argaud and flat-wick burners in combination with independent deflecting cones or air-directors; but my invent-ion relates to the use of deflecting plates where this cone or air-deflector is dispensed with.

What I claim, and desire to secure by Letters Patent. is- I 1. In an Argand or other like round-wick burner, the employment of a cap or flange, arranged near the top of the wick-tube, substantially in. the manner described,- so as to deflect and change the direction of the current of air passing upward around the wicktube, and cause it to impinge at an angle upon the flame, as set forth. 7

2. The combination, with an Argand-burner, of an air-deflecting shieldor cap below the flame, through which cap a portion of the air will pass in a divided state to the flame, as shown and set forth.

3. The combination, with an Argand-burner, of a deflector or cap below the flame, constructed substantially as herein described, so as to cause the air to pass up around it in a continuous sheet, at varying distances from the wick-tube, as set forth.

4. The combination, with the sleeve connected with the chimney-seat and gallery, of the deflecting cap, supported upon a shoulder or offset formed on said sleeve, substantially as shown and set forth.

In testimony whereof I have signed my name to this specification before two subscribing witnesses.
